  1. Telephone & Exchange Tester ETET 30 ELEKTRNIKA ETET 30 is a central office installed touch screen controlled instrument intended to identify the cause of subscriber complaints. • The operator can test: ● The circuits of exchange ●The operation of DSLAM ●The parameters of line ● The subscriber’s phone set ● The noise spectrum • Test groups: ●User Side Tests ●Exchange Side Tests ●Modem Detection ●ADSL Test ●VDSL Test For details click on the corresponding keys.

  2. ELEKTRNIKA User Side Tests of ETET 30 The user side tests are intended: ●To test the access line when the subscriber’s phone is in on-hook state. ●To test the subscriber’s phone set with his assistance. Selectable Modes: ●DMM ●TDR ●Spectrum analyser ●Test Call For details click on the corresponding keys.

  3. ELEKTRNIKA User Side DMM Measurements Voltage Measurements ● AC, DC voltages between wire A and GND ● AC, DC voltages between wire B and GND ● AC, DC voltages between wires A and B Insulation Resistance Measurements ● Between wire A and GND (RAE) ● Between wire B and GND (RBE) ● Between wires A and B (RISO) with normal and reversal polarity Capacitance Measurements ● Between wire A and GND (CAE ) ● Between wire B and GND (CBE ) ● 2 Pole capacitance between the wires ● Load capacitance CL Automatic Test Sequence ● Pressing the Auto key ETET 30 performs the previous measurements. Continuity Measurement ● In this mode ETET 30 performs loop resistance measurement. If the loop resistance lower than a preset threshold acoustic warning is provided. Test results exceeding the designated limits are marked with red color.

  4. ELEKTRNIKA User Side TDR In case of a cable break or short circuit the first task is to identify the location of fault. First of all the operator has to know that the fault is inside the building of central office or it is somewhere else on the line. The purpose of the User Side TDR is to test the access line. Two modes are provided: ●Normal mode for the localization of shorts and brakes. ●Long time mode for the localization of loose contacts.

  5. Spectrum Analyser ELEKTRNIKA The purpose of the User Side Spectrum measurement is to get information about the disturbing voltages on the line. In that mode ETET 30 can detect the presence of ADSL, ADSL 2+ or VDSL modem at the user’s home when the DSLAM is disconnected from the subscriber’s line.

  6. User Side Test Call ELEKTRNIKA In this mode the subscriber’s telephone set can be tested with his assistance. The operator should call and communicate with the subscriber. Loop Test Ask the subscriber to keep the line and wait. Start loop resistance and loop current measurements with the Loop Test key. Loudness Test Send test tone with the Send 800 Hz key. After a while ask the subscriber’s opinion about the loudness. Dial Test Sometimes the subscribers complain that they are connected to another subscriber instead of the one they wanted to call. The purpose of that test is to identify the reason of the malfunction. Press the Dial Test key. Ask the subscriber to press the numbers on his key board after each other.

  7. ELEKTRNIKA Exchange Side Tests of ETET 30 ETET 30 provides: ●The testof ringing, register and line feed circuits of exchange. ●The location of wiring problems inside the building of central office. Selectable Modes: ●DMM ●TDR ●Ringing Test ●Register Test For details click on the corresponding keys.

  8. ELEKTRNIKA Exchange Side DMM Measurement Voltage Measurements ● AC, DC voltages between wire A and GND ● AC, DC voltages between wire B and GND ● AC, DC voltages between the wires Loop Current Measurements ● When the loop is closed. Automatic Test Sequence ● Pressing the Auto key ETET 30 performs the previous measurements. Continuity Measurement ● In this mode ETET 30 performs loop resistance measurement. If the loop resistance lower than a preset threshold acoustic warning is provided. Test results exceeding the designated limits are marked with red color.

  9. ELEKTRNIKA Exchange Side TDR In case of a cable break or short circuit the first task is to identify the location of fault. First of all the operator has to know that the fault is inside the building of central office or it is somewhere else on the line. The purpose of Exchange Side TDR is to test the wiring inside the building of central office. Two modes are provided: ●Normal mode for the localization of shorts and brakes. ●Long time mode for the localization of loose contacts.

  10. ELEKTRNIKA Ringing Test In this mode the operator can dial up any phone number using a service line. Typical applications: ● The subscriber complains that the loudness of ringing is not enough. To check the proper operation of exchange the operator dialsthe user’s phone number and ETET 30 measures the ringing voltage. ●The operator would like to use ETET 30 as a normal phone.

  11. ELEKTRNIKA Register Test Sometimes the subscribers complain that they are connected to another subscriber instead of the one they wanted to call. The purpose of that test is to identify the reason of the malfunction. In this mode ETET 30 sends a test call from the subscriber’s line to the service line and indicates the appearance of ringing voltage.

  12. Modem Detection ELEKTRNIKA Function: In that mode ETET 30 can detect the presence of ADSL, ADSL 2+ or VDSL modem at the user’s home when the DSLAM is disconnected from the subscriber’s line. Principle of operation: The modem detection is based on spectrum measurement. ETET 30 recognizes the hand shake signals rhythmically transmitted by the modem.

  13. ADSL Modem Tests ELEKTRNIKA By means of the “Golden Modem” of ETET 30 we can check the proper operation of DSLAM. ETET 30 offers two test options: ● Synchronization Test providing information on the training process and the actual state of line. In this mode there isn’t data transfer between the local and public network. ●Automatic Test providing detailed information on the quality of data transfer between the local and public network. The actual connection profile and the LAN parameters can be modified before starting the test. For details click on the corresponding keys.

  14. ELEKTRNIKA ADSL Synchronization Test When the synchronization test mode is selected the Modem Status display appears and ETET 30 automatically starts the synchronization. The training process takes a while. During this time the actual modem status information is displayed. The status indicator shows the actual state of synchronization: RED The line is in Idle State (No synchrony) GREEN (blinking) The training is in progress GREEN (Continuous) The synchronization is completed Finishing the training process ETET 30 provides detailed line diagnosis.

  15. ELEKTRNIKA Automatic ADSL Test When the automatic test mode is selected the Modem Status display appears and ETET 30 automatically starts the synchronization. The training process takes a while. During this time the actual modem status information is displayed. xDSL connection Indicator RED No synchrony GREEN (blinking) The training is in progress GREEN (Continuous) The synchronization iscompleted Link IP Status Indicator RED There is no data transfer YELLOW Trying to establishdata transfer GREEN Successful data transfer ETET 30 provides: ●Ping & Trace test ●Detailed line diagnosis ●Browsing possibility For details click on the corresponding key.

  16. ELEKTRNIKA Editing of ADSL Profile ETET 30 supports the synchronization in all ADSL modes and connection types. Supported ADSL Modes As a default ETET 30 supports the synchronization in all ADSL modes but the operator can disable one ore more of them. Selectable connection types: In ADSL mode ETET 30 supports five connection types.
